title = "Communication in Shared Memory: Concepts, Definitions, and Efficient Detection",
abstract = "Optimizing the communication behavior of parallel applications has emerged as an important topic in parallel processing. In shared memory architectures, threads communicate implicitly through memory accesses to shared memory areas. The communication behavior can be improved by mapping threads that communicate a lot to processing units that are close to each other in the memory hierarchy, such that they can benefit from shared caches and faster interconnections. An important aspect of such a communication-aware thread mapping is the accurate and efficient detection of communication in shared memory. Previous work used impromptu definitions, without an evaluation of the complexities of different communication types. In this paper, we perform an in-depth, systematic evaluation of communication in shared memory, focusing on its architectural effects. We present an efficient way to detect communication, which is orders of magnitude faster than a cache simulator, while maintaining a high accuracy.",
